You do realise this is never going to happen? Especially not with countries that are already running on budget deficits. If you want the roads to be privatised (whom then eventually will setup tolls) be my guest... but leave me out of it lmao.
Where is the funding for all this coming from again? Remind me why councils for example in the UK, are broke and barely investing in this stuff?
Ah... yeah. Lets get real.
